13 Claims.

the following description when read in the light of the accompanyingdrawings of a machine constituting one embodiment of the invention,while the scope of the latter will be more particularly pointed out inthe appendedclaims.

In thedrawingsc- ,Fig. 1 is a front elevation of a machine constructedaccording to the invention .with parts broken away;

Fig. 2 is a side elevation of the machine ac cording to Fig. 1;

Figs. 3 and ll are respectively sections on the lines 3-3 and t--i ofFig. 1;

Fig. 5 is a bottom View of the Fig. i on an enlarged scale;

Fig. 6 is a section on the line t-t of Fig. 5;

Fig. 7 is a bottom view of the spring release mechanism shown in Fig. l;and

Figs. 8 and 9 show two examples of ornamented trimmings.

Heretofore ornamented trimmings for shoes commonly have been made bycementing to the body of a narrow leather strip a superimposed narrowerstrip of leather of contrasting color,

guide shown in a desired design. Such trimmings, however, besides beingexpensive to fabricate, are, because of their relatively greatthickness, dificult to bend transversely about corners in applying themto the shoe, and are lacking in durability because 4G or the tendency ofthe strip of ornamentation to separate from the body of the strip,particularly when the trimming is bent around a corner and as aconsequence slightly wrinkles or buckles.

The attempt to ornament shoe trimmings by the use of ink or color, or bythe use of granular, powdered, or flocculent materials, has heretoforeproved unsuccessful because, among other things, of failure uniformly tocover the leather or other material with ink or color, or apply thedesign with proper or uniform relation to the edges of the strip, orsecure a sharp line of demarcation between the color or other materialand the body of the strip.

According to the present invention the strip i constituting the body ofthe trimming has formed which narrower strip is sometimes cut to form,

thereon a design which may consist of a continuous or interrupted thinlayer of flaccid material more particularly described in the copendingapplication above referred to. The design in which this ornamentation isformed may take a multitude of forms, among which is a simplecontinuousband 3, shown in Fig. 8, or an interrupted. band consisting of dots 5,shown in Fig. 9. It has been found in the vast majority of cases thatbest effects are secured when the edges of the ornamentation areslightly spaced from the edges of the strip, as indicated in Figs. 8 and9. This, because the strip commonly will be relatively narrow, say aboutwide, will necessitate placing of the ornamentation with considerableaccuracy and uniformity with relation to the edges of the strip, asotherwise the attempt to ornament the strip would result in an unsightlyproduct.

Referring to the drawings of the submitted embodiment of the invention,a frame is provided comprising a base i at opposite sides of which arevertical standards d, the latter being roughly C-shaped, as shown inFigs. 2- and 3, so as to provide openings l i for a purpose which willhereinafter appear. Carried by the standards ii are bearings is for ashaft l5 driven by a suitable belt pulley ill, this shaft carryingbetween the standards a roll it for applying the layer of ornamentationto the strip i. Conveniently this roll may consist of a copper cyllnderwhich, as illustrated, is provided with a circumferential band itpreferably formed by knurling, or, if desired, by a photogravureprocess, to cause the band to consist of a multitude of closely spacedminute depressions. The particular band 2! shown is that used forprinting the continuous ornamental band shown in Fig. 8-, and it will beunderstood of course that if the ornamentation to be formed is in thenature of an interrupted band. the hand All will be likewise interruptedas, for example, may be formed corresponding to the ornamentation shownin Fig. 9.

Cooperating with the roll ii is apresser memher, which herein takes theform of a roll it adapted to contact with the upper side of the strip ibeing operated upon. As shown, the roll 23 is mounted'on a shaft 25having reduced diameter end portions 21, each of which latter carriesthe inner race it of a ball bearing, the

outer race it of which is received in a. suitable recess formed in theblock 33. .As showrnthe shoulder 35 formed by the reduced diameterportion 2'17 of the shaft abuts with the inner race- 29 so that the ballbearing serves also as a thrust 5 bearing for preventing longitudinalmovement of the shaft 23. Conveniently each ball bearing is held inplace by a plate 31 secured to the inner side of the \block 33.

As shown, the blocks 33 are carried at the ends of levers 39 positionedat the outer sides of the standards 9, said levers being pivoted to thelatter at 3|. As shown, the free end of each lever 39 has attachedthereto one end ofa tension spring 43, the other end 'of which isattachedto the frame at 45 so as normally to urge the roll 23 away fromthe-roll I9. Herein the blocks 33 are rigidly connected by a yoke member31 which extends over the top of the standards 9. the opposite arms ofthe yoke being operatively secured to the levers by suitable screws 49.As shown, extending between the standards 9 and rigidly carried therebyis a bar i, the latter having a screw threaded perforation 53 intowhich'is screw threaded an upwardly projecting bolt 53, the latterextending freely through an opening 51 at the upper portion of the yoke41. At its upper end the bolt 35 fixedly carries a head 59 sewing as theupper abutment for a rather stout compression spring 8| having but aslight degree of expansion, the lower abutment for which spring isformed by a lever 63 having an opening 33 through which the bolt 55freely extends. At its under side the lever 93 carries a pair of cam orwedge members 61 having the. inclined faces 69 and flat" faces II, thesemembers 61 cooperating with bosses I3 on the upper side of the yoke 41.

In the position of parts shown in'Fig. 1 of the drawings the spring GI,reacting between the abutments afforded by the head 59 and lever 63,

presses the yoke 41 downwardly, which causes the upper roll 23 to beurged toward the lower roll I9 with a force greater than that with whichthe springs 43 urge the upper roll 23 away from the roll I9.

As illustrated, the lever 93 is elongated so that one end 15 thereofaffords a convenient handle grip by which the operator is enabled torotate the lever from the position of parts shown in Fig. 1 to suchposition that the cams G1 are no longer in contact withthe bosses 13,under which condition the spring 3| expands to beyond its limit ofexpansion by movement .of the lever 33 downwardly relative to the yokep", and therefore no longer acts to urge the upper roll 23 downwardly,the latter consequently under these conditions being moved upwardly bythe springs 33 so as to relieve the pressure on the strip I. Folvaryinthe force with which the spring 8| urges the roll 23 toward the roll I9,the bolt 39 may be rotated so as readily to adjust it verticallyrelative to the bar 5| when the cam lugs 81 are out of contact with thelugs I3, a lock nut 11 being provided for holding the bolt in itsadjusted positions. This adjustment, which moves the head 59'constituting the upper spring abutment vertically upor down as desired,causes; when the lever 93 is moved into the position of parts shown inFig. 1, the spring 3| to exert an adjusted force on the lever 93andccnsequently on the roll 23.

Herein the lower roll 2i dips into a container 19 containing coatingmaterial to be applied to the strip I. For wiping the roll I9 clean ofall coating material, except that which is in the minute depressions ofthe band 2|, 'a suitable doctor may be employed, the latter asillustrated being in the form of a flexible doctor knife 9i carried by ashaft 33 which is rotatably and reciprocally mounted in bearings 33,these bearings being mounted for sliding movement in slots 31 in thevertical standards 9. As shown, the shaft at one end thereof has aradially extending arm 99 carrying a weight 9| which urges the shaft torotate in the bearings 85 in such direction as to press the doctor knifeagainst the roll I9, or by rotating the arm 89 in an upwardly directionthe doctor knife may be permanently held out of contact with the roll.When the parts are in the position shown in Figs. 1 and 3, the bearings35 tend to slide to the right, as viewed in Fig. 3, against the ends ofbolts 92 screw threaded into the standards 9. By turning the bolts 92the bearings may be adjusted toward the roll I9.

Herein, for reciprocating the shaft 93 which carries the doctor knife3|, the shaft I5 for the lower roll I9 carries, at its end opposite thepulley II, a worm 93 which drives a worm wheel 95, the latter beingrotatably mounted on a spindle -(not shown) carried by a bracket 91(Figs. 1 and 2) extending from the adjacent standard .9 of the which atthe under side of the lever is supported a roller I I3 positionedbetween collars Iii on the shaft BI so th t when the lever is oscillatedthe shaft II 'will be reciprocated. As shown, the roller H3 is.positioned directly above the shaft 8|, which arrangement permits theshaft to be adjusted toward the roll I3 by means of the adjusting screws92 and permits the shaft to be rotated in its bearings by thecounter-weight 9 without interference. 7

Suitable tensioning means are preferably employed for the strip I, saidmeansherein comprising a pair of spaced lower arms I I1, each of whichat one end thereof is pivotally supported by a pin II9 carried at theinner side of the adjacent standard 9 .(see Figs. 3 and 4). The spacedarms I I1 herein carry spaced rollers I2I over which the strip I passes.Likewise pivoted to the pins II9 are upper arms I23 which carry spacedrollers I25 in staggered relation to the other rollers I2I, so that theweight of. the upper rollers and arms I23 contacting with the lowerrollers serves to tension the strip. Normally the arms II'I rest on pinsI21 projecting from the adjacent standards, while one or the other ofthe upper arms I23 carries a set screw I29 the end of which is adaptedto contact with one of the arms I" so that the tension on the strip maybe regulated. When initially threading the strip through the machine,the upper arms I23 with their associated rollers may be readily raisedby swinging the arms about the pivot pins H9, and, if desired, both setsof arms and rollers may be moved out of operative position with relationto the strip by swinging them about the pivot pins II9, allowing thearms to hang downwardly in a vertical position.

For guiding the strip. in operative relation with the band 2Ion the rollI9, the machine herein illustrated is provided with a guide carried by abar I3I, which latter, as shown, is of rectangular cross-section and iscarried at opposite ends thereof' by the several standards 9. As shown,

a ioasoa tions we, whichlatter with the body of the member form a slotreceiving the bar; The member i 33 at one end is provided with a sloti3? through which passes a screw I39 tapped into the bar l3| so that themember 433 may be secured in different adjusted positions longitudinallyof the bar. At the end of the member I33 opposite the slot li'i is alaterally and upwardly projecting flange i ll which serves as the guidefor one edge of the strip l. Lying on the member (I33 is a member M3having an elongated slot 545 through which passes a set screw M7 forsecuring the member M3 in adjusted relation to the member H3. As shown,the member Hi3 has the side flanges M9 which with the body of the memberform a slot receiving the member H3. Further, the member lid is providedwith a-laterally projecting portion mil having a downwardly projectingmarginal flange i! which is notched as shown at i153 so as to be out ofcontact with the bar idi. By loosening the set screw it! and adjustingthe member Hi3 relative to the member 133 the space between the flangesBill and Ml can be varied to accommodate difierent widths of strips i,while by adjusting the entire guide member relative to the bar iti uponloosening the set screw use, the guide may be adjusted relative to theband it on the roll id.

In operation, the roll ill is coated with the coating material in thecontainer it, all of this material which adheres to the roll being wipedtherefrom by the doctor knife l5! except such material as-is forced bythe knife into the minute depressions forming the band M or otherwiseenters these depressions.- The surface of the roll i9 forms a supportforthe entire width of the strip l, while the upper roll 23 under theinfluence of the springs ti, when the parts are in the position shown inFig. 1, exerts considerable pressure on the strip so as to force it intocontact with the rim portions of the minute depressions in the surfaceof the roll E9. The strip i being operated upon is pref.-

erably initially coated with a pyroxylin compound or other suitablematerial, while the coating material applied by the machine preferablycontains a solvent for the coating on the strip, with the result thatthe coating material drawn from the minute depressions by the squeezingand releasing action of the rolls on the strip adheres to the latter andintegrally unites therewith without noticeable spreading. The strip isfed by action of the two rolls which grip it, and the feeding at anytime may be interrupted by disengaging the wedge cams ti" from the lugsill on the yoke ll by the operator swinging the lever it. To insure thatthe ornamentation "formed on the strip is in the exact center thereof,after the strip is once run through the rolls it may be reversedtransversely and again run through them so as to avoid any possiblesheet of inaccurate alignment of the strip guide with the band 24;

It will be understood that wide deviations may be made from the form ofthe invention herein described without departing from the spirit of theI invention.
